How to clear chart data?

[User (Legacy)]

Hi! 

I'm trying to convert an application that used ChartFX 3.0 to ChartFX 98. 

Since the package is not delivered yet I'm using the trial version. 

And I faced the following problem. 

The below code worked with ChartFX 3.0, i.e. it cleared chart data and the 

chart window displayed "No data available message". However, the code 

doesn't work with ChartFX 98, i.e. the chart window contents do not change. 

What am I doing wrong? 

What is the correct way to remove all series and points from the chart? 

Thanks, 

Serge 

if (nNewPoints == 0 || nNewSeries == 0) 

{ 

    // no points --> empty chart 

    int nSeries = m_pChartFX->NSeries; 

    int nPoints = m_pChartFX->NValues; 

    m_pChartFX->OpenDataEx((CfxCod)COD_VALUES, nSeries, nPoints); 

    m_pChartFX->OpenDataEx((CfxCod)COD_XVALUES, nSeries, nPoints); 

    m_pChartFX->CloseData(CfxCod(COD_VALUES | COD_REMOVE | COD_SMOOTH)); 

    m_pChartFX->CloseData(CfxCod(COD_XVALUES | COD_REMOVE | COD_SMOOTH)); 

    return; 

}
